Low Humidity And Operate Cost Deep dehumidification Liquid Desiccant Air Conditioning
1.Introduction
Heat pump type liquid desiccant air conditioning is an air dehumidification equipment with solution (lithium bromide, lithium chloride, calcium chloride, etc.) as the working fluid, The unit is driven by a heat pump and adopts advanced solution dehumidification technology,through the solution to absorb or release moisture to the air, to achieve the adjustment the humidity of air.It is not an ordinary fresh air ventilator,it is a fresh air treatment equipment integrating cold and heat source, dehumidification section, regeneration section, filter section, air supply section and exhaust section,It is flexible in application, simple in operation, and energy-saving, and is suitable for occasions where dehumidification and cooling are required in harsh environments such as air pollution, toxicity, and odor.
2.Product or system advantage
1) Save energy and protect the environment
a. The working temperature of the dehumidification section is 18-25 °C, which avoids the energy waste caused by the need for reheating when the dehumidification temperature is too low, and improves the cooling capacity of the heat pump;
b. Dehumidification ,cooling and solution regeneration are driven by heat pumps, and more than 90% of the condensation heat is recycled, which greatly improves the cooling efficiency of the system and does not discharge waste heat to the surrounding area.
2) Strong dehumidification ability and wide application range
The air can be cooled and dehumidified or heated to dehumidify, and the minimum can reach 2.1g/kg.
3) Improve indoor air quality
a.The high-concentration salt solution can kill most bacteria, viruses and other molds, and the killing rate can reach more than 99%, providing a favorable defense weapon against airborne diseases such as influenza and coronavirus;
b. Constant temperature and humidity, humidity deviation +-1%.
4) Stable performance
a. The salt solution does not decompose or volatilize, the moisture absorption and regeneration efficiency are stable, and it is less affected by the changes of the parameters of the fresh air and return air, the dehumidification performance is not attenuated, and the service life is long.
3.Product features:
1. The counter-flow air supply design has high gas-liquid heat exchange efficiency, and the volume is more compact compared with the cross-flow air supply design, and the equipment occupies a smaller area of the computer room;
2. The super absorbent core is made of polymer fiber material through a series of processes such as compression molding, high temperature carbonization, bonding, curing, etc. It has the advantages of anti-aging, corrosion resistance, mildew resistance, and long service life;
Combined with the design of counter-flow air supply, it can effectively solve the common liquid-carrying problem in cross-flow air supply;
3. Advanced solution concentration control technology, the unit has stronger and more accurate dehumidification capacity, and the minimum fresh air humidity can be controlled at 2.1g/kg.
4. International standard, reliable operation:
a. The solution tank is integrally formed, and there is no risk of air leakage and liquid leakage;
b. The heat exchanger is made of titanium tube, which will never rust.
c. Refrigeration components, controller components, water pumps, fans and other main components are all internationally renowned brands, which are stable and reliable
